MILK AND CREAM SEPARA'IOR.

Application filed October 29, 1927. Serial N0. 229,642.

This invention aims to provide a novel device adapted to be placed in amilk bottle or like container, to separate the milk from the cream, sothat the cream may be poured off. The invention aims to improve theconstruetion of the separator, and to provide novel means for operatingthe separator so that it can be turned into a position in which it canbe inserted readily into the restricted neck of a milk bottle.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the inventionappertains. I

lVith the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed may be made within thescope of what is claimed, without depart ing from the spirit ofthe'invention.

In the drawings Figure 1 shows in side elevation, a device constructedin accordance with the invention; A

Figure 2 is an elevation wherein thestruc ture is viewed at right anglesto the showing of Figure 1;

Figure 3 is a transverse section wherein the separator appears in topplan;

Figure 4 is a bottom plan of the separator;

Figure 5 is a sectional view showing the parts as they will appearwhilst the separator is being inserted into the neck of the bottle;

Figure 6 is a top plan of the structure arranged as shown in Figure 5,parts being in section.

The device forming the subject matter of this application includes asupportor standard 4, in the form of a rod, the lower end of the support4 being flattened as shown at 11, and being twisted as indicated at 27,to form an anchor and stop 28. At its upper end, the support 4 has ahandle in the form of a finger loop 5. The numeral 1 marks an operatingmember, which may be a rod, provided at its upper end with a finger loopor handle 2. The operating member 1 is supplied at a point near itsupper end with a transverse guide 3 mounted on the support 4. Theconstruction is such that the operating member 1 can slidelongitudinally on the support 4 and also swing a little, to an acuteangle with respect to the support 4, as shown face of the body 14. Acorresponding intermediate lower reinforcing plate 16 cooperates withthe lower surface of the body 14, andthe intermediate plates 15 and 16are connected, through the body 14, by securing elements 17. Upper Vlateral reinforcing plates'18 are mounted on the upper surface of theflexible body 14, and on the lower surface of the body 14 are mountedlower lateral reinforcing plates 19, the plates 18 and 19 preferablybeing made of metal, and

being connected, through the body 14, by

securing elements 20. The longitudinal edges of the plate 16 (Figure 4)are spaced,

as at 21, from the longitudinal edges of the plates 19. In a similarway, as shown in Figure 3, the longitudinal edges of the plate 15 arespaced from the longitudinal edges of the plates'18. The construction issuch that although the separator 12 may be folded along two linesparallel to the line A-B in Figure 4, the separator is rigid in adirection at right angles to the line A-B. The plates 161915 18 formmetal reinforce ments of less area than the flexible body 14, so thatthere is left a flexible margin 22 in the body 14, this margin beingadapted to make a tight fit when the article is intro duced into a milkcan.

The reinforcing plate 16 has a hole 23 that registers with a hole 24 inthe flexible body 1.4 of the separator 12. The plate 15 of the separatorhas a notch 25 that exposes the hole 24 in the body 14; A rectangularlip 26 is formed on the plate 15 at the base of the notch 25 andoverhangs the hole 24. An arm 8 is formed on the plate 15 at the base ofthe notch 25 and extends away from ed at 9 with the arm 8 at a pointinter-' mediate the ends of the arm. The. arm 8 and the pivot elements 9and 10 constitute means whereby the operating member 1 and the standard4; are pivotally connected; with the separator 12 in offset relation tothe separator. The links 29 are pivot-ally connected with the part 28 ofthe support 4, and it is on this account that the part 28 is alluded toas an anchor. The links 29 diverge from the part, 28 and are pivotallyconnected with ears 30 on the plates 18 of theseparator 12.

The spring 7 expands andproduces relative longitudinal movement betweentheopcrating member 1 and the standard 4:, until the arm 8 of theseparator 12 abuts against the top 28 on the lower end of the support 4.Under such circumstances, the separator 12 stands at right angles to thepartsl and 4, as indicated in Figure 2.

In using the. device, the thumb and one of the fingers of an operatorare placed in the loops 5 and 2, and relative longitudinal movementbetween the standard 4 and the operating member 1 is brought about. Thisoperation tilts the separator 12 until it is above the separator 12 maybe poured oil, Whilst the cream is being. poured out of. the bottle, noappreciable amount o-fmilk will flow through the registering holes 23and 2 1 of the separator 12, because no air can get in through the holes23-24. W'hen,

however, the cream has been poured oil, and

when it is desired to remove the separator.

12 from the milk bottle, the holes 28- 24 permit themilk togetthroughthe-separator 12, and the folding of the separator into theposition shown in Figure 5, for removal, will be facilitatedaccordingly.

What is claimed is 1. In a device of the class described, a support, anoperating member, means for connecting the support and theoperatingmember for relative longitudinal movement, a foldable separator, meansforconnecting the support andthe operating member pivotally to theintermediate portion of the separatorin oif set relation to theseparator,

links forming a pivotal connection between the support and the sideportions of the separator, and spring means for imparting relativelongitudinalmovement to the sup port and to, the operating'member to dispose the separator fiat andina position approximately at right angles tothe support, and to the operating. member.

2. In a device of the classdescribed, a

foldable separator, the intermediate portion of which is provided with.a projecting arm, a support pivoted to the outer end of the arm at apoint intermediate the ends of the support, links forming apivotalconnection between one end of the support andthe side portions ofthe separator, an operating member, means for mounting the operating memher on. the support for movement longitudinally of the support, andmeansfor pivotally connecting the operating member with the arm at avpoint intermediate the ends of the arm. n

In testimony'that we claim the foregoing as our own, we have heretoafiixed our signatures. I
